FIG. 1.

Alignment of the Cryptosporidium SSU rRNA gene diagnostic fragments obtained with primers CPBDIAGF and CPBDIAGR for C. parvum anthroponotic genotype 1, C. meleagridis, C. parvum zoonotic genotype 2, and C. wrairi. Only the first 300 columns of the alignments are shown, as the remaining columns were identical for all of the genotypes. Dashes indicate gaps, and dots indicate bases that are identical to the C. parvum genotype 1 bases. The GenBank accession numbers for the C. parvum genotype 1, C. meleagridis, C. parvum genotype 2, and C. wrairi sequences shown are L16997, AJ242472, AJ242471, and U11440, respectively. In the complete SSU rRNA coding sequence for the anthroponotic genotype of C. parvum (GenBank accession no. L16997), the region shown corresponds to positions 602 to 901.
